Virtual reality is an artificial environment that is created with software and presented to the user in such a way that they suspend belief and accept it as a real environment. On a computer, virtual reality is primarily experienced through two of the five senses: sight and sound. The user becomes part of a virtual world or is immersed within this environment and whilst there, is able to manipulate objects or perform series of actions. The simplest form of virtual reality is a three-dimensional image that can be explored interactively at a personal computer, usually by manipulating keys or the mouse so that the content of the image moves in some direction.
The VR breakthrough we're seeing this year is in large part due to breakthroughs in the technology of the components. Innovations in the display technology, stimulation technology, network technology, sensor technology, artificial functions as well as computer graphic technologies have allowed VR to become more than just a fad. Today, virtual reality systems require extremely expensive hardware and a custom software configuration. The reason you need a high powered VR computer is that you are pushing a massive amount of pixels. These VR devices have two HD low persistence displays refreshing 90 times per second and that is a lot of individual pixels. The frame rate is king when it comes to a VR desktop. If it dips below the refresh rate of the screens in the headset, you are going to feel ill. Therefore, before investing in a VR PC or tablet or laptop, it is advisable to check the specifications which can meet the requirements of your virtual reality applications today and in the future.
There are many different types of virtual reality systems but they all share the same characteristics such as the ability to allow the person to view three dimensional images. The aim is for a seamless connection between the user's head and eye movements and the appropriate response. This ensures that virtual environment is both realistic and enjoyable.
